CASH REGISTER AND INDICATOR.

.JPECIFICATION forming part of Letters Patent No. 374,780, dated December 13, 1887.

Application filed June 30, 1887. Serial No. 242,986. (No model.)

To all whom it may concern:

Be it known that I, DANIEL DAVIS, a citizen of the United States, residing at Elmira,

.in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Cash-Registers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is afront elevation of my improved cash-register, partly in section to show a portion of the interior mechanism; Fig. 2, a central sectional elevation thereof; Fig. 3, a rear view of Fig. 1, with the back of casing and door removed to show the interior mechanism thereof; Fig. 4, a rear view showing the position of the registering-dials; Fig. 5, a detail view of the gear-wheel, pawl, and ratchet, showing them secured to the central shaft. Fig. 6 is a detail view of the frictionwheel and dog. Fig. 7 is atop plan of Fig.6. Fig. 8 is a transverse sectional view in detail, showing the drawer operating mechanism. Fig. 9 is a view at right angles to that of Fig. 8.

The present invention has for its object to provide a cash-indicator in which the amount of the purchaser is registered, and one in which the operation of the mechanism will be both perfect and reliable; and the invention consists in the details of construction substantially as shown in the drawings, and hereinafter described and claimed.

r In the accompanying drawings, A represents a suitable case of any preferred design, which contains the operating parts of the device,or more especially the registering mechanism, said frame being supported upon a hollow base, B. A panel, C, is secured to the front of the frame A, and covers the entire upper portion thereof, and is provided with a suitable opening in the middle to allow some portions of the work to project through, as shown at a, Fig. 2, and to this panel the upper or penny dial-plate, E, is attached, as

shown in Fig. 1.

' To the panel (land in front thereof is attached, in any suitable manner, a second panel, D. The upper portion of the panel D is of much less thickness than the lower portion, so as to form a space between the two panels for a portion of the operating mechan-. ism, as shown in Fig. 2, said panel serving as a support for the lower or dollar dial, F, to which it is attached in any convenient man- 1161.

VVithin the frame A are located suitable standards, I) c, to which the gearing and other portions of the cash-register are connected. The spindle or shaft d, which has its bearings in the standards I) c, has connected to its front end a lever, G, said lever extending up above the panel 0 and over the same, and is provided with a pointer, e. Below the shaft d is a similar but longer shaft, f, which also has connected to its front end a lever, H, which projects above the top of the panel D and over the same, and is provided with a pointer, g, the levers above described being loosely attached to their respective shafts. The upper ends of the levers terminate in tube-shaped projections h, to which the pointers are connected, said tube being left open on the inner side to admit of spring-levers i,which are connected to the pintle j of the pointers. These levers i are provided with a suitable handle or knob, as shown in Fig. 1, and a curved spring, k, bears on the pivotal portion of the lever to keep the tooth Z of the lever engaged with the teeth m on the segmental plate I. By this means the levers are held, and also the pointers,in any desired position when the latter are set to any desired figure on the dial.

The notched or toothed plates I are secured to and back of the panels G D, respectively, and their sole object is to retain the pointers at the position set by the engagement of the teeth upon the levers i with the notches of the plate, which are assisted by means of the spring bearing on the levers, as hereinbefore described.

The shaft f, to which the lever H is connected, is provided with a gear-wheel, J, and a ratchet-wheel,p, with which engages a pawl, 12, retained in engagement with the teeth by means of the spring 0, said pawl and spring being connected to the gear-wheel J, as shown in Fig. 5. The gear-wheel J engages with a pinion, q,on a short shaft, r, which has its bearing in the uprights b c, and on this shaft is mounted a gear-wheel, s, which engages with a pinion, t, on the shaft (2, the several gearwheels and pinions being located between the standards or uprights above described.

To adjust the device ready for action, the pointers e g are brought to zero, as shown in Fig. 1, while the gearing is held from turning backward by means of the pawl a and spring a, the former engaging with the teeth upon a large ratchet-wheel, K; and when the lever G is raised and moved to the right by means of the small hand-lever i a pawl, 10, pivoted to said lever, will engage the teeth of the ratchet wheel K and turn the shaft d, to which it is connected. A spur-wheel, L, is attached to the ratchet-wheel K, which will turn pinion a. The small pinion t on shaft d will turn the gear-wheel s on shaft r, and the pinion q on said shaft will turn thegearwvheel J, said wheel turning loosely on said shaft when turned backward; but when turned to the right the ratchet-wheel 19 will turn the shaftf by means of the pawl a. Upon the shaftf, near its front end, is a frictioirwheel, M, and above this friction-wheel and to the lever H is pivoted a dog, I), said dog being acted upon by a spring, 0. When the lever H is turned to the right, the dog will come in frictional contact with the periphery of the wheel M and turn the shaft f instantly at any point; but when the lever is turned backward it will slide freely around the shaft while the latter remains stationary. It should be understood that the levers G H are loosely connected to their shafts,

and only when moved in one direction the shafts will turn.

The ratchet-wheel K is provided with two hundred notches, to represent the number of cents in two dollars, so that when turned halfway around it will point out one hundred cents, while by means of the back gearing the lower shaft,f, will cause the pointer g to indicate one dollar on the dial N at the back of the register, from the fact that said shaft will turn only one hundredth part the distance of the shaft d; but when one or more even dollars are to be shown the lever H is used, while the upper lever remains stationary and its pointer at zero, and not used except when odd cents are required.

By means of the gearing hereinbefore described, if the upper lever, G, is moved from zero to one hundred on the front dial, E, the gear-wheel L on the shaft (1, engaging with pinion a, and the former having double the number of teeth of the latter,will give the pointer 5 f on the back dial, 0, one revolution, while the pointer 9 will move only one-twentieth as far, or at the rate of twenty dollars to one. Now the next move on back register is to jump from twenty dollars up to five hundred dollars, and to provide for this I employ a ratchet-wheel, P, having twenty-five teeth with figures from twenty dollars to five hundred dollars arranged in rotation and on line with each tooth, as shown in Fig. 4. The ratchet-wheel P revolves on a stud, d, projecting from the standards 0, and is operated by a dog, h, on the shaft f. \Vhen the lower or twenty-dollar pointer, 51, is at zero, the pennypointerf will also indicate zero and one of the numbers on the wheel P appear in sight.

In practice the wheel P is entirely covered up, with the exception of a sufficient opening in the case or frame to show one only of the figures thereon, although in Fig. 4 a greater portion of the wheel is shown in order to enable its construction to be understood. When the twenty-dollar hand or pointer 9 makes a complete revolution, the wheel P will move so as to show the twenty-dollar mark thereon, and at the nextcomplete revolution of the hand 9' the forty-dollar mark will be shown on the wheel, and so on up to five hundred dollars, when the wheel P makes a complete revolution. After the wheel P has made its complete revolution to indicate the numerals five hundred the wheel and pointer may be again set after the register has been taken.

I provide the register with an automatic back board, S, of any preferred shape and-ornamentation, andhas the words The Amount of Your Purchase See Dials placed thereon in large plain letters in order to attract the attention of the customer making thepurchase. This back or sign board is vertically movable, and has connected to its lower end by suitable pivots the rods i, said rods being pivoted at their lower ends to swinging levers k, which are secured to the ends of a transverse board, T, extending across in the vacant space above the drawer Q. To the board T is connected one end of a bent arm, U, said arm extending down in the rear of and pressing against the center of the drawer by means of the coiled springs Z,whieh press on the board T, so that when the drawer is released by the mechanism hereinafter deseribed it will be forced out of the hollow base B. This drawer, which is designed for containing bills of various denominations, is held within the hollow base B by means of bolts m, said bolts being pivoted to brackets on the partition V, and have located under their ends springs a, so as to press upwardly on this end and retain the belts in engagement with the drawer to'prevent its being withdrawn. These bolts are operated by the two upright rods 0, extending up just a little above the levers G H, or rather above their lower ends or edges, so that when said levers are brought back to zero, as shown in Fig. 1, the curved bolts m m will be raised out of their notches and the drawer spring open, and at the same time the sign-boards will be thrown up by means of its connection with the swinging levers k, and the bell V will be rung at the same time.

The mechanism for operating the bell is as follows: The lever G is provided with aratchet-whee1, p, with which engages a pawl, q,

pivoted to the outer end of the hand-lever z, said pawl being held in engagement with the teeth of the ratchet-wheel by a spring, 1'. The hammer s is connected to a pivoted lever, t, held in engagement at its upper end with the teeth of the ratchet-wheel 1) by means of the spring a, the bell-operating mechanism above described being clearly shown in Fig.3. When the hand-lever z is pulled out sufficiently to allow the tooth thereon to clear the notches on the plate I, the ratchet-wheel 10 will turn the distance of one notch, and by means of the lever t engaging therewith the bell will be caused to ring by the action of the spring u on the lever.

It should be noticed that the wheel I? is moved the distance of one tooth at every complete revolution of the pointer g by means of the dog oon the shaft f, said dog engaging with the teeth on the wheel 1?, and turns with the shaft, as shown in Fig. 4:.

. The hollow base B at its front side is provided with a hinged door or lid, R, to obtain access to the receptacle Y, which contains the coins.

In the construction of the complete device it is evident that manychanges may be made that come within ordinary mechanical skill, and I therefore do not wish to be understood as confining myself to the precise construction of the mechanism shown. The gearing is also capable of modification, and a different arrangement of-gear-wheels and pinionsniay be employed, as found best adapted to the purpose, these changes being made without departing from the principle of my invention.

'Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. The shafts d f,connected together by suitable gearing, in combination with said gearing, the levers Gr H, provided with pointers e g, respectively, hand-levers z, provided with tooth Z, and the notch-plate I, said handlever being retained in engagement with the notches on the plate by means of a suitable spring, substantially as and for the purpose specified.

2. The shaft f, provided with lever H, having pointer g,in combination with the frictionwheel M and spring-pressed friction-dog b, pivoted to the lever, substantially as and for the purpose described.

3. The frame A, provided with standards b c to form bearings for the several shafts, said frame being also provided with index-panel G, and index-panel D, attached to the front of the panel C and having its upper portion of less thickness than its lower portion, the whole being supported upon ahollow base, B, and the lever G, carried by a shaft journaled in said standard and extended above the panel C, substantially as and for the purpose set forth.

4. The lever G,provided with ratchet-wheel p and pawl (1, connected to the hand-lever i, in combination with the bell W, hammer s, pivoted lever t, and spring to, substantially as and for the purpose set forth.

5. The combination, with the movable sign:

board S, of the pivoted arms is, rods '5, for

connecting the board to the arms, the transverse board T, the curved arms U, attached at one end to said board T, and the other bearing against the rear end of the drawer,springs Z, pressing on said board T, and suitable bolts for locking the drawer closed, substantially as and for the purpose specified.

6. The curved bolts m, pivoted to suitable brackets on the partition V, and the springs n, in combination with the upright rods 0 and the levers G H, provided with suitable pointers, substantially as and for the purpose de scribed.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DANIEL DAVIS.
